Answer
1. (5);
Total number of students with Mechanical specialisation in 2013 = 2544
Total number of students with Electronics specialisation in 2013 = 1428
Reqd % = (2544 / 1428) * 100 = 178.15 = 178%
2. (2);
Reqd ratio = 780 / 880 = 39 : 44
3. (4);
Number of students with IT specialisation = 340 + 300 + 260 + 340 + 180 + 260 + 220 = 1900
Number of students with Mechanical specialisation = 280 + 360 + 200 + 260 + 320 + 320 + 380 = 2120
Difference = 2120 – 1900 = 220
4. (3);
Total number of students in Institutes P, Q and R with IT specialisation in 2013
= 340/100 * 115 + 300/100 * 122 + 260/100 *110
= 391 + 366 + 286 = 1043
5. (1);
Total number of students in Institute Q = 240 + 300 + 360 = 900
The number of students liking music from Institute Q = 900 * 5 / 18 =250
6. (1);
The number of boys in Institutes P, T and U with Electronic specialisation = 340
7. (4);
Check options one by one.
(A) Total revenue generated from Online version by Magazine T = 209 + 217 + 185 + 156 + 139 + 144 = Rs 1050 thousand
Total revenue generated form Printed version by Magazine T = 152 + 186 + 116 + 129 + 187 + 154 = Rs 924 thousand
Online version revenue is more than Printed version revenue. Thus, (A) is not true.
(B) Total revenue generated by all the given magazines in January = 169 + 163 + 201 + 145 + 136 + 141 + 209 + 168 + 152 + 209 + 131 + 184 = Rs 2008 thousand = Rs 2008000
Total revenue generated by all the given magazines in June = 172 + 141 + 142 + 163 + 178 + 243 + 211 + 177 + 154 + 144 + 151 + 194 = 2070 thousand = Rs 2007000
Difference = 2070 – 2008 = 62 thousand = Rs 62000. Hence, B is true.
(C) Neither type of magazines shows constant increase in its revenue from previous month.
Hence (C) is not true. Thus, only (B) is true.
8. (3);
Total revenue generated from Online version by Magazine U = 184 + 190 + 219 + 236 + 111 + 194 = Rs 1134 thousand
Total revenue generated from Printed version by magazine U = 131 + 98 + 118 + 174 + 168 + 151 = Rs 840 thousand
Reqd % = (1134 - 840) *100 / 840
9. (4);
% rise from Jan to Feb (305-277) * 100 / 277 = 10.10%
Similarly, Feb to Mar (326-305) * 100 / 305 = 6.88%
March to April = (375-326)* 100 / 326 = 15%
April to May = (405-375)*100 / 375 = 8%
May to June = (421-405) *100 / 405 = 3.9%
Hence the required answer is March to April.
10. (2);
The ratio of revenue generated by Magazine P in July is same as the ratio of revenue generated by Q in March.
Reqd ratio of Q from printed version to online version in March = 204 : 144 = 17 : 12
Revenue generated by P in July from printed version = 108000*17/12 = 153000
11. (1);
Reqd ratio = (171 + 139 + 149 + 223 + 217 + 190) : (113 + 128 + 196 + 132 + 187 + 168) = 1089 : 924 = 33 : 28
12. (5);
Total revenue generated from printed version by Magazine P in January and April = 169 + 163 = 332
Total revenue generated from Online version by magazine S in February and June = 223 + 177 = 400
Reqd % = (400-332)*100 / 400 = 17%
